Efficiency Evaluation of Beijing Intelligent Traffic Management System Based on super-DEA

Intelligent traffic management system (ITMS) is an effective measure to improve the urban road transport system operating efficiency. With the practice of Beijing urban intelligent traffic management system, this paper takes the urban transportation systems, socio-economic system and energy environment system as the input system, and sets the road traffic management efficiency and urban transport putting indicators as the output systems. The paper develops a corresponding super-efficiency DEA model, and examines the coordination degree between the ITMS level and urban development. The field data of Beijing from 2000 to 2010 are used for empirical analysis. Based on the model results and the practices of Beijing, the paper comparatively analyzes the relative effectiveness trend of urban transportation and the subsystems of economy and energy environment. It aims to provide some references for the future development and construction of the Beijing ITMS.

摘要智能交通管理系统是提高和改善城市道路交通系统运行效率的一项有效措施。本文以北京城市智能交通管理系统应用为背景，选取城市交通系统、社会经济系统以及能源环境系统为投入系统，相关道路交通管理效率及城市交通外放性指标组成产出系统，建立了相应的超效率DEA评价模型，研究分析城市智能交通管理系统水平与城市发展的协调程度。应用北京市2000–2010年的实际数据进行了实证分析，根据模型计算结果，结合北京市的发展实践，对比分析了城市交通与经济及能源环境子系统的相对有效性变化趋势，以期为北京城市ITMS未来的发展建设提供一定的参考借鉴。
